Title: Control device of material feeding device
Inventor: KAWAMURA ATSUSHI
IPC: B21D43/09
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To set the driving speed of a material feeding device automatically according to the driving speed of a processing machine. SOLUTION: A material feeding device 2 feeds a material to a processing machine 1 intermittently by an electric servo motor (a motor 3). A control device 5 of the material feeding device 2 receives a starting signal from the processing machine 1. The starting signal indicates the feeding timing of the material in the operating cycle of the processing machine 1, and its pulse width is proportional to the operating speed of the processing machine 1. The control device 5 has a measuring means to measure the pulse width of the starting signal, a memory means to memorize the rotational speed of a motor, and a control means. The control means takes out the rotational speed corresponding to the measuring result of the measuring means, and drives the motor by this rotational speed.  The driving speed of the material feeding device 2 is set in a reasonable value to the processing speed of the processing machine 1 side, and the feeding speed follows to the processing speed. Consequently, a high accuracy can be realized without depending on the experience and the sense of a worker.

Title: Multiple thread milling cutter
Inventor: GOTO HARUO
IPC: B23G5/18
Filed: 1989-12-26
Abstract: PURPOSE:To cut even a comparatively long thread with a high efficiency and high accuracy, by making the plural thread cutting parts provided with their separation each other in the peripheral direction slided each other in the axial direction under the conditions that the pitch on the rotating locus of a cutting edge continues in the axial direction same as the pitch of a forming thread. CONSTITUTION:The recessed places 26, 28, 30 of a tip fitting seat are mutually slided in the axial direction and tips 14, 16, 18 are fitted to a tip fitting seat without the rotating locus of a cutting edge 24 being duplicated mutually in the axial direction and so that the pitch in the axial direction may continue at the pitch of a forming thread. In the case of cutting a lot of threads simultaneously, three tips are separated in the peripheral direction and slided mutually in the axial direction. So that, the thread cutting parts by each tip 14, 16, 18 are slided in the length direction of a thread and the length cut simultaneously by an individual tip is short. Consequently, the cutting resistance acting on each tip becomes smaller and also the cutting resistance of a milling cutter 10 whole body is dispersed, the reduction in the working accuracy is restrained with the lightening of a deflection deformation and a high accuracy processing becomes possible.

Abstract: PROBLEM TO BE SOLVED: To increase tolerances for position adjustment of transparent substrates arranged opposing to each other and also to facilitate discovering a defect of a short circuit and repairing it by forming a conductive layer formed of a transparent material via an insulation film in a region between a video signal line and the other electrode arranged adjacent to the video signal line. SOLUTION: In a region between a video signal line 3 and a reference electrode 14 arranged adjacent to the video signal line 3, a conductive layer 100 partly overlapping the other electrode adjacent to the video signal line 3 is formed of ITO via protection film 19. Thus, an electric field generated by the video signal line 3 and the reference electrode 14 ends at the side of the conductive film 100 and is not formed extending up to the side of the liquid crystal. And since this conductive film 100 is formed of a transparent material composed of ITO, even when a defect of a short circuit occurs between the video signal line 3 and the reference electrode 14, it is easily found out via the conductive film 100 and is also easily repaired.
